Most of the time, Fox's hit show "Glee" offers a sunny vision of high school. It's a musical, after all.

DAVID GREENE, HOST:

MONTAGNE: The characters paid tribute to Finn Hudson, who was played by the late actor Corey Monteith. He died of a drug overdose in July.

GREENE: The episode gave fans a chance to grieve; 7.4 million viewers tuned in, a huge spike from the previous week. Despite the ratings surge, though, "Glee's" creators have announced next season will be the last.

MONTAGNE: So the big closing number for the show's finale might be "Hello Goodbye"?

GREENE: Or I'd say "Don't Stop Believing." What do you think? Send us your thoughts on Twitter, #NPRGlee.
